Abstract

A vehicle with a self-contained cooling and heating capability and a tenting feature for sheltering and controlling the temperature at a given location. Warm air is directed out of a heat chamber through a telescopic tube arrangement which may be horizontally piovoted for improved heat direction. The tube arrangement may also be vertically tipped upwardly and downwardly to maximize directional control of heat output. Heat for melting snow may thereby be directed to specific locations. The tenting arrangement provides elevated and focused heating and little heat waste.

       a telescopic ejection tube apparatus attached to said heat chamber, said tube apparatus having a caster bearing, with a central opening, fixedly attached on the heat chamber exterior about the top opening, said caster bearing central opening being coincident with the heat chamber top opening, said tube apparatus having a spring collar mounted onto the caster bearing over the caster bearing central opening.  
     
     
       6. A vehicle as recited in  claim 5 , wherein: 
       the ejection tube apparatus has a telescoping tube mounted on and pivotally attached to said caster bearing spring collar, said caster bearing adapted to horizontally pivot thereby pivoting the tube, said caster bearing being driven by a motor mounted on the heat chamber top and electrically connected to and controlled within the equipment and control cab.  
     
     
       7. A vehicle as recited in  claim 6 , wherein: 
       said telescoping tube having a proximal end, a distal end, and a cylindrical side wall defining a tube interior, said cylindrical side wall having an opening formed therein near to the tube proximal end, said opening providing direct access to the tube interior, said tube opening beings coincident with the heat chamber top opening.  
     
     
       8. A vehicle as recited in  claim 7 , further comprising: 
       a deployable canopy section attached to the tube distal end.  
     
     
       9. A vehicle as recited in  claim 8 , wherein:
